IPv6 deployment delay

[Shiver Me Whiskers 15]

Hello everyone, new subscriber to AirVPN ;-)

 

The reason I got this service is to "punch through" the new(ish) West-European DS-Lite CGN (Dual-Stack Lite Carrier-Grade NAT), which my provider has pushed me with their modem/router upgrade a few days ago.

Basically, I only have an IPv6 address and that's it ! No IPv4 whatsoever (only private address 192.168.x.x and double NAT...)

 

The biggest problem with CGN is that port forwarding no longer exists on IPv4, meaning byebye incoming connections for PLEX, p2p, xCast Radio, sFTP, etc... things that I do enjoy keeping on my 24/7-on PC.

 

So, VPN it is, so at least I can have a private IPv4 that receives port forwarding from the IPv4 Internet.

However, what happens now is that my packets go through quad conversion, double private addresses, double shared public v4... it's a mess:

 

VPN private v4 | OpenVPN tunnel encapsulation <-> Router v4 private address <-> DS-Lite Part1 | CPE encapsulation in v6 <-> v6 network to carrier <-> DS-Lite Part2 | CGN extract to v4 <-> v4 network to AirVPN server <-> OpenVPN extract to public v4 <-> v4 network to the destination ... finally my packet gets there (and then all the way back)

 

This is to be honest a ridiculously complex structure that causes unneeded high latency, unstable speed and making my CPE to crap out on occasion and drop packets like crazy... (even on the first node, my guess is it warms up and throttles during high usage)

...and it could be avoided by completely skipping the CPE<->CGN encapsulation by connecting to AirVPN straight from IPv6:

 

VPN private v4 | OpenVPN tunnel encapsulation <-> Personal v6 "real" address <-> v6 network to AirVPN server <-> OpenVPN extract to public v4 <-> v4 network to destination ... DONE !

 

 

Hope this gets resolved soon !

Thanks and sorry for the long post.
